| Abstract: | Encoding method is used to find candidate codewords in turbo decoding of product codes, and performance of product codes built with single-error-correcting block codes is provided. The effect on performance is studied when the number of candidate codewords is different. The difference between two met in estimating the extrinsic information of those bits without compete codewords is analyzed when the enco method or Chase-II algorithm is used. |
